It's got 125804 km on the clock. Fuel filter was changed about a year ago. Fuel consumption seems normal, but I do sometimes get a whiff of unburnt fuel. So, it's definitely the injectors, you reckon? What's the best way forward?

Given the mileage, the symptoms, and the occasional smell of fuel, a defective injection valve/injector is certainly a very strong possibility. While injector cleaner might offer a temporary improvement, a proper diagnosis and potential replacement at a workshop is the recommended course of action to ensure optimal fuel delivery and engine performance. I'd advise against DIY repairs on the fuel rail.

Cheers for the advice! Bit the bullet and took it to the shop. Turns out the cold start injector was indeed kaput. New injector fitted, and it's running like a dream now. Cost me 515€, but worth it for the peace of mind!

Indeed, poor cold starting and rough running are common indicators of injector issues. How many kilometers are on the vehicle? Has the fuel filter been replaced recently? Have you noticed any changes in fuel consumption or any unusual smells?
